Lesson 29 of 44

A portfolio manager (PM) decides what a portfolio holds and how much of each, and is accountable for its performance. PMs run mutual funds, ETFs with active strategies, pension portfolios, hedge fund books and private wealth accounts. They draw on analysts' research, risk teams and traders, but the final investment decisions and the responsibility for results are theirs. It is one of the most senior and scrutinised roles in finance.

At multi manager hedge funds, PMs often run their own books with strict drawdown limits; losing a set amount, sometimes in the mid single digits as a percentage of allocated capital, can mean capital is cut or the PM is let go. See Risk, Position, Loss and Drawdown Limits.

Skills needed#

  • Investment judgement: turning research into decisions under uncertainty.
  • Risk management: seeing the portfolio as a whole. See Diversification.
  • Discipline: sticking to process through drawdowns. See Discipline.
  • Communication: explaining decisions to clients and teams.
  • Leadership: managing analysts and working with traders.

Typical path#

  1. Analyst roles, on the sell side or buy side, building research skills.
  2. Senior analyst with responsibility for a sector or strategy.
  3. Co portfolio manager or managing a small sleeve of capital.
  4. Portfolio manager with full responsibility.

Professional credentials such as the CFA charter are common among fundamental PMs, though not required. Quant PMs usually come from research roles. See Quant Trader and Quant Researcher.
